Yeah I'm ambivalent on this one. On the one hand, the preponderance of evidence supports the theory that Roundup ain't great for the environment or anything in it. On the other hand, California is the place where coffee comes with a cancer warning. What the market is saying, effectively, is that Monsanto is a toxic asset... which has more to do with public opinion than anything else.
I'll say this: I never heard anybody say fuckall about Roundup in ten years of working. Yesterday? Fuckin' 5 conversations along the lines of "how could they do this to us?" so the argument could be made that the judge effectively sent a fat fuckin' message.
